Yes, any good synthetic such as Meguiar's #20, Klasse AIO, Klasse SG, Z-2 etc.... will give you good results on rims as they are more durable than carnaubas.
Tom, to be perfectly honest the only thing that has blown me away in the past two to three months is the look of some of the pics of the Blackfire system. Looks real nice. The other thing that is worth mentioning is that I had two wheels professionally refinished at the Wheel Collision Center. They charged me about $100 for my 17 inch wheels. I had two of them done and I must say that the results are spectacular. Identical to the factory finish and when I had them balanced with my tires they were absolutely perfect both times. Very impressed. I believe that this company is in the New England area. Laters buddy.
